Dell Latitude E7270 Battery Drop

Question

Hi Everyone Out There,

I'm facing an issue with my Dell Latitude E7270. I purchased a used one and it seemed alright. When I use the laptop after charging it 100%, it works smoothly until 50%-60% and after that the battery suddenly drops to 7%-8%. Also while charging, the same problem can be seen. After getting charged up to 60% it goes directly to 100%.

I purchased a new battery for it, it is giving me a backup of 3 hours & after that it also flicks and goes directly to 7-8%. I switched from adaptive charging to standard charging, this time it got up to 70% and then went straight to 100%.

I also updated the BIOS to latest version but all in vain.

I hope I can find someone here who knows the solution to this problem.

Looking forward to hear from y'all.

Thanks.

I have the same problem on a dell e7270.. the original battery had a drop at 50% to 6 to 8% I ran battery monitor several times and it seem to get lower each time .. meaning even ti 30% before drop .. so I decided to buy a brand new genuine battery and the drop in that battery is 52% to 6%… very strange .. logically the dell batteries must have bad calibration as there lasting 4 hours before the drop off …
